Subject: [PATCH] Restore compatibility with Kotlin plugin broken in
 3796f503b014f8268f9e992.

Base class with generic type was extracted. There used to be method 'updateComponent(PsiElement, Comparator)' but after refactoring it became 'updateComponent(T, Comparator)' which is effectively 'updateComponent(Object, Comparator)' in bytecode. To fix compatibility, it is enough to override the method with necessary signature in the old class.
